The efficient way of cooling
Benefits
Efficient
- Efficient distillation due to complete integration into the BUCHI rotary evaporation system
- Saves time thanks to instant start with automatic and dynamic pressure adjustment without waiting until chiller reaches it’s set temperature
Ecological
- ECO-mode: saves energy and reduces heat emission by switching into a stand-by mode when not in use
- No water consumption
- Maximizes distillation capacity while reducing solvent emissions due to intelligent integration of all process parameters using the Interface I-300 / I-300 Pro
Interactive
- Seamless plug & play integration into:
- Fully automated BUCHI Rotavapor® R-300 systems including all process parameters
- BUCHI extraction and Kjeldahl solutions
Features
Can I reduce the energy consumption of the evaporation system?
Yes, the ECO-mode is an integral part of the BUCHI Rotavapor R-300 system. Both bath and chiller enter a stand-by more after a pre-defined period of time and are restarted automatically when required.
What refrigerant is used in the recirculating chiller?
The refrigerant in all BUCHI recirculating chillers is R-134a (1,1,1,2-Tetrafluoroethane). This is a haloalcane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane), but with less ozone depletion potential.
When is it recommended to work with a recirculating chiller?
When you use a solvent like petroleum ether, a recirculating chiller should be implemented if the tap water is warmer than 15 °C. The temperature difference between the boiling point of the solvent and the cooling water temperature should be 20 - 25 °C in order to achieve a good condensation of the solvent in the condenser and to keep a good solvent recovery.
What is the recommended cooling liquid in the recirculating chiller?
The mixture on the coolant is very important. If the mixture is not correct, it may freeze in the chiller and block or destroy the pump. Therefore we recommend a mixture of ethylene glycol and water 30/70 (%V). This mixture has a freezing point of -14 ° C. As the F-100 has a fix temperature of 10 °C also water is ok.
How much heat is generated by a chiller?
The compressor in the chiller generates heat. The heat is blown out of the unit by a fan. The heat emission depends on the cooling capacity of the chiller. The heat emissions are:
- F-100: max. 300 W
- F-105: max. 300 W
- F-305: max. 300 W
- F-308: max. 500 W
- F-314: max. 1000 W
- F-125: max. 1800 W
In standby mode is the compressor and also the circulating pump turned off and do not generate any heat emissions.
